Key Parameters

Substitute Part Grouping Explanation

Substitution of the 84688-903SLF is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Total position count (108 positions)
• Contact pitch (0.079" / 2.00mm)
• Row configuration (5 rows)
• Mounting method (Board Edge, Through Hole, Right Angle)
• Termination style (Press-Fit)
• Contact layout (90 Signal, 18 Ground)
• Current rating (1A)
• Operating temperature range (-55°C to 105°C)
• Flammability rating (UL94 V-0)
• Series family (Metral® 1000)

The substitute part 84688-103LF meets all these criteria while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 84688-103LF is a direct functional equivalent to the 84688-903SLF across all critical electrical and mechanical parameters. Selection between these parts should be based on the following factors:

Product Status: The 84688-903SLF is obsolete, while the 84688-103LF maintains active product status. For new designs and ongoing production, the 84688-103LF is the appropriate choice.

Compliance and Certifications: The 84688-103LF provides RoHS compliance, whereas the main part does not specify this status. Both parts maintain identical flammability ratings (UL94 V-0) and moisture sensitivity levels (MSL 1).

Contact Finish: The 84688-103LF specifies gold plating at 30.0µin (0.76µm), providing enhanced corrosion resistance and contact reliability compared to the unspecified finish of the main part.

Packaging: The 84688-103LF is supplied in tube packaging, which may differ from the original part's packaging configuration.

Regulatory Compliance: The 84688-103LF is REACH Affected, indicating compliance with current regulatory requirements, while the main part is REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 84688-103LF be used as a direct replacement for the 84688-903SLF?

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters: 108 positions, 0.079" pitch, 5-row configuration, board edge through-hole mounting, press-fit termination, 90 signal and 18 ground contact layout, 1A current rating, and -55°C to 105°C operating temperature range. The 84688-103LF is the active equivalent.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), contact finish specification (unspecified vs. gold plating at 30.0µin), RoHS compliance status (unspecified vs. compliant), and packaging format (unspecified vs. tube). Functionally and electrically, the parts are equivalent.

Q: Does the gold plating on the 84688-103LF affect compatibility?

A: No. Gold plating is a contact finish enhancement that improves corrosion resistance and contact reliability. It does not affect mechanical or electrical compatibility with mating components designed for the 84688-903SLF.

Q: Are there any temperature or current rating differences?

A: No. Both parts maintain identical operating temperature ranges (-55°C to 105°C) and current ratings (1A per contact).

Q: What is the significance of the RoHS compliance on the 84688-103LF?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This is relevant for applications subject to environmental and regulatory requirements in the EU and other jurisdictions.

Q: Can I use the 84688-903SLF if the 84688-103LF is unavailable?

A: If the 84688-903SLF is available in inventory and your application does not require active product status or RoHS compliance, it remains functionally equivalent. However, for new designs and long-term supply assurance, the active 84688-103LF is recommended.

Q: Are there any packaging considerations when switching to the 84688-103LF?

A: The 84688-103LF is supplied in tube packaging. Verify that your assembly and handling processes are compatible with this packaging format before implementation.
